splotter
Read SPEC scan files from the command line: list scans, pull values by column name, look up metadata and draw mesh maps that combine several scans.
Three meshes and two line scans of the made-up file from splotter demo, on one map (reproduce the figure).
The name comes from splot, the plotting command in SPEC. splotter is an independent project and is
not affiliated with or endorsed by Certified Scientific Software, the makers
of SPEC.
Install
Requires Python 3.13 or later. Install it as a command with uv tool install splotter or
pip install splotter, or create a small uv project:
uv init --no-workspace --python 3.13 splotter-demo
uv add --directory splotter-demo splotter
Quick start
No measured data ships with splotter. splotter demo writes a made-up SPEC file, the same one every
time. Run this from the directory where you created splotter-demo:
$ uv run -q --directory splotter-demo splotter demo demo.spec
wrote demo.spec
wrote demo_fwhm.csv
$ uv run -q --directory splotter-demo splotter info demo.spec 1 -c imtot Sample_X Sample_Y --top 1 --csv
point,imtot,Sample_X,Sample_Y
301,97699.0,0.4,-0.3
That is the brightest point of the mesh in scan 1. Every command takes the SPEC file first:
splotter info FILE --last 20 # scan list: start time, duration, points, command
splotter info FILE 2032 669 # time, motors and counters of one point
splotter info FILE 2032 -c imtot Sample_X # values by column name
splotter info FILE 2032 --meta # #T, #Q, #R lines and #UXML metadata
splotter mesh FILE 2032 2036 --log # map of several scans
splotter rock FILE 2033 --counter imroi1 # rocking curve
